An optical fiber having a core that has a graded refractive index profile is disclosed a clad surrounds the core and traps light within the core a difference between differential mode delays (dmds) at wavelengths of about 1300 nm and about 850 nm within the core is increased in a radial direction. Synopsis: the graded-index(grin)fiber has a core material whose reflective index varies with distance from the fiber axisthe light waves in a grin travel through the fiber in the ocillatory fashion of the above figure. In the following picture of a graded index fiber two different modes are depicted one is a higher mode which is propagating towards the core-cladding interface and one is through the higher refrac. Fujikura’s large core fibers can offer you optical energy delivery solutions of high power laser transmission applications.
